Spray foam insulation seals your home tight — cutting energy bills by up to 50%, eliminating hot and cold spots, and paying for itself within 3 to 5 years. Homeowners across the Upstate are making the switch.
From attics to crawl spaces, new builds to retrofits — we match the right foam to your specific needs.
With an R-value of approximately 3.7 per inch, open cell foam expands to fill every gap and cavity in your walls and attic. It excels at air sealing and sound dampening, making it ideal for interior applications. It's our most cost-effective option for homeowners who want serious comfort and noise reduction improvements.

Our premium option delivers R-values of 6.5 to 7 per inch — nearly double open cell. Closed cell foam acts as a moisture and vapor barrier while adding structural rigidity to your walls. It's the best choice for crawl spaces, basements, and exterior-facing applications where moisture resistance is critical.

Your attic is the single biggest source of energy loss — responsible for up to 40% of wasted heating and cooling. Our spray foam creates a seamless air-sealed envelope that eliminates drafts, prevents ice dams, and makes upstairs rooms as comfortable as the rest of your home. Your HVAC system will finally stop working overtime.

Uninsulated crawl spaces introduce moisture, mold, pests, and cold floors into your living space. Spray foam encapsulation seals out humidity and blocks entry points for insects and rodents. You'll notice warmer floors in winter, better indoor air quality year-round, and fewer allergy triggers throughout your home.

Metal buildings, warehouses, retail spaces, and offices all benefit from spray foam's ability to eliminate condensation and regulate temperature. We handle large-scale projects with minimal disruption to your business operations, ensuring code compliance and long-term energy savings that improve your bottom line.

We partner with builders across the Upstate to coordinate timelines, meet building code requirements, and deliver a tight building envelope from day one. Your new home starts efficient — and stays that way for decades.

Closed cell spray foam applied to foundation walls creates a waterproof, insulating barrier that transforms your basement into usable living space. It resists mold growth and keeps your foundation protected from the ground up.

For garages — whether attached or detached — we create a thermal barrier that protects adjacent living spaces and makes the garage itself more comfortable.

Air leaks in walls, attics, and crawl spaces let conditioned air escape constantly. That's the equivalent of leaving a window cracked open 365 days a year.
Homeowners with poor insulation pay $500 to $1,000 more annually in heating and cooling costs. That money goes straight through your roof — literally.
Gaps in your insulation invite condensation, which feeds mold colonies and accelerates structural decay. These problems affect your family's respiratory health and your home's value.
If your upstairs is sweltering in summer and freezing in winter, it's not your HVAC — it's your insulation. Your system compensates by running harder, driving up wear and costs.
Every crack that leaks air is also an entry point for insects, rodents, pollen, and dust. Spray foam seals these pathways permanently — no gaps, no voids, no invitations.
Don't let poor insulation drain your money, comfort, and property value. Spray foam seals your home tight and starts saving you money immediately.

"Every project we do is a reflection of who we are. If I wouldn't put it in my own home, we're not putting it in yours."— Owner, Extreme Spray Foam
"Our power bill dropped from around $280 to $165 the very first month after Extreme Spray Foam insulated our attic and crawl space. We live in a 1970s ranch in Mauldin and had been dealing with sky-high bills for years. I honestly didn't think the savings would be this dramatic — but the numbers don't lie. Best investment we've made in this house."
"Our upstairs bedrooms were unbearable in the summer — easily 8 to 10 degrees hotter than the main floor. We had two window units running constantly just to keep the kids' rooms tolerable. After the attic was sprayed with open cell, the temperature difference disappeared completely. The whole house feels balanced now. Wish we'd done it sooner."
"The crew showed up right at 8 AM, laid down coverings everywhere, and had our entire crawl space done by early afternoon. They explained every step, answered all my questions without rushing me, and left the place spotless. You can tell these guys actually care about doing things right. Already recommended them to three neighbors."
